THE GOLDMUND GOLDCUBE

6.3 Main line ohase inversion.
The sonic quality of your GOLD CUBE may be slightly improved
if the main AC line is properly connected. Try to invert the plug
of your amplifier, using a special adapter.
We recommend that you proceed caref ully to try this. You must
do it in combination with the speaker polarity and/or with absolute
phase switching to be sure of the result.

SAFETY FEATURES
The GOLDMUND GOLD CUBE amplifier provides very sophisticated
features to protectthe amplifierandthe speaker against all
kind of mishandle or comoonent failure.
Protection against DC.
The GOLD CUBE is a DC-coupled amplifier. lf the associated
preamplifier is badly designed or defective (often true for the
tube preamps), the speaker could be damaged. The detection
circuit of the GOLD CUBE is totally immune to any sonic effect
but will immediately switch off the speaker if such a malf unction
occurs.
The speaker will be immediately and automatically reconnected
as soon as the perturbation disappears.
Protection against HF oscillations.
In the same way, the speaker will be disconnected if a large
amount of high frequency oscillation is present and shows a
danger forthe tweeters, even if these frequencies remain unnoticed.
The amplifier returns to normal if the oscillation disappears.
Protection against short-circuits.
lf one output is short-circuited by accident and the current
becomes too high, one of the rail fuse may blow.
In this case, the small LED located at the top ofthe defective fuse
lid will glow.
To replace the defective fuse, switch the amplifier off for 1O
minutes f irst. Then open the top f use cover with a coin or a large
screwdriver. The f use loader is then accessible under the golden
cover and must be removed by turning it off with a screwdriver.
